[0002] Thermoplastic materials generally refer to materials that have a certain degree of plasticity after reaching a certain temperature and can be shaped after cooling. However, the efficiency of traditional manual tape laying of thermoplastic materials is extremely low, so there are automated tape laying machines. However, since the tape laying head needs to lay and heat special-shaped materials, it is difficult for current automatic tape laying machines to lay special-shaped materials evenly, resulting in uneven laying. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a tape laying head, which can adjust the discharge speed of the discharge roller according to the different forces applied to the first drive roller, so that the tape laying head can evenly lay special-shaped materials.

[0027] Reference below Figures 1 to 4 A tape laying head according to an embodiment of the present invention will be described.

[0028] The tape laying head according to the embodiment of the present invention includes a frame 100, a feeding roller 110, a first driving motor 120, a transmission roller and a tension sensor. The feeding roller 110 is rotatably arranged on the frame 100 for feeding; the first driving motor 120 is connected to the feeding roller 110 to drive the feeding roller 110 to rotate for feeding; the transmission roller includes a first transmission roller 210 and a second transmission roller 220, the first transmission roller 210 and the second transmission roller 220 are arranged on the frame 100, and the feeding roller 110, the first transmission roller 210 and the second transmission roller 220 are arranged in a triangle, so that the material can be hooked on the first transmission roller 210 through the feeding roller 110, the first transmission roller 210 and the second transmission roller 220; the tension sensor is connected to the first transmission roller 210, and is used to detect the force applied to the first transmission roller 210, and the first driving motor 120 adjusts the rotation speed of the feeding roller 110 according to the force measured by the tension sensor.

[0029] For example Figure 1 , Figure 2 and Figure 3As shown, a feeding roller 110, a first transmission roller 210 and a second transmission roller 220 are provided on the frame 100. The first drive motor 120 is connected to the feeding roller 110 to drive the feeding roller 110 to rotate. The feeding roller 110, the first transmission roller 210 and the second transmission roller 220 are arranged in a triangle, so that after the strip 700 is fed out through the feeding roller 110, it is hooked on the first transmission roller 210 and then flows out from the second transmission roller 220 in the reverse direction. When the strip 700 is laid on the special-shaped material, the use speed of the strip 700 will change. Since the use speed of the strip 700 and the discharge speed of the discharge roller 110 do not match, the force of the strip 700 on the first drive roller 210 on both sides of the first transmission roller 210 changes. The tension sensor is connected to the first transmission roller 210. When the forces on both sides of the first transmission roller 210 are measured to be different, the rotation speed of the first drive motor 120 is adjusted, thereby adjusting the rotation speed of the discharge roller 110 and adjusting the discharge speed, so that the discharge speed matches the material use speed, so that the tape laying head can evenly lay the special-shaped material.
